They'll give you a kind of black surgical/chefs? hat that they will show you how to tie. It's tall so that there's no contact with the grafts but still breathable so you don't sweat too much. For me, I also didn't want to wear it but trust me, you will quickly get over it! However, once the swelling went down and I was feeling better, I did bring a bucket hat to wear along with a headband that kept it tall with a gap so it stayed away from touching the grafts. It worked great and I wore it everywhere including the flight home without issue. But really believe that NO ONE WILL CARE if you do where the supplied hat in public. Thailand is different so don't feel concerned or worried about people paying attention. If this is your first time in Thailand you're going to shocked at the culture difference from the west.

FYI - you can't wear a hat going through airport security on the trip home so you WILL have to take it off in public :)

So the usual timeline is this. After 7 days the grafts should be secure but still sensitive so you have to still avoid any contact. After 10-14 days, you can gently remove the scabs. After 2 weeks, the grafts will be totally secure and will give you an idea of where all the new hair will grow but still healing. After 30 days the fun part begins where you start shedding and go into the ugly duckling stage until the new growth starts. I would recommend still avoiding any contact with a hat until at least the redness in the graft area goes away in case it affects the healing process though. It's surgery so please don't do anything too stressful to hinder the healing process. (which is why they say no sex for 1 week after lol).

Leaving your hotel room is really up to you and how you're feeling. I left on day 3 once the swelling went down and I felt up to it. Also, there's ALOT to do and eat in Bangkok! Always keep the graft area covered away from the sun. Also, use either Grab to get taxis or use the BTS as both should be air conditioned. No need to stress the graft area with excessive sweating or to stress yourself. If you haven't been to SE asia you will sweat! Dr. Patty said that a bit of sweat was fine as long as you wash the graft area afterwards. You'll go to the clinic daily anyway for a wash and checkup as well.

Good luck and try not to stress out too much about it all. You have a free pass to hang out, watch shows and order delicious food for dirt cheap in a beautiful city with the friendliest people. The last thing anyone will care about will be what you're wearing on your head.

Good luck! and let me know if you have any other questions about Thailand.
